8 a.m. update: Tangled on Hwy. 280; 169 a mess in Edina

Traffic on southbound Hwy. 280 is backed up to Hwy. 36 due to a crash involving a semitrailer truck and a bus at Broadway Street. Motorists are being directed to use Broadway Street, so expect lots of traffic on nearby city streets.

Hwy. 169 in both directions is clogged in the vicinity of Valley View Road and 76th Street due to several spinouts. Roads reported to be extremely slick there.

A ramp jam is in progress on the ramp from southbound 94 to the 4th/7th Street exit.

I-494 is quite slow and icy between Cedar Avenue and Hwy. 110. That is in both directions, so plan on 24 minutes to through there.
